摘要： Disclosed is a device for cooling an internal combustion engine in which circulation of cooling water is halted until the cooling water reaches a predetermined temperature, wherein decline in the durability of a radiator, which is caused by thermal strain that occurs when circulation of the cooling water is restarted and the cooling water is introduced into the radiator, is suppressed. An internal combustion engine (10) comprises an electric pump (23), a water temperature sensor (92), a radiator (21), and a thermostat (22). The water temperature sensor (92) detects a cooling water temperature (THW). The radiator (21) is capable of circulating the cooling water between the radiator (21) and an engine cooling system (13). If the cooling water temperature (THW) is equal to or greater than a valve opening temperature (TZ), the thermostat (22) opens and the cooling water is introduced into the radiator (21). An electronic control device (91) performs control in such a way that the discharge pressure of the cooling water is increased by the electric pump (23) before the thermostat (22) opens and cooling water is introduced into the radiator (21).

摘要： An image forming apparatus includes a control device that calculates a developing ability of the developing device based on a detection value detected by an optical detection device from the plural toner patches. The control device adjusts an image formation condition based on the calculated developing ability. A factor detection device is provided to detect a contributing factor that causes the developing ability to largely change after the last adjustment of the image formation condition. The control device controls image formation such that when the factor detection device does not detect the contribution factor and a developing ability calculated this time is different from that calculated last time (as to a part of the plural toner patches), the plural toner patches are formed based on a prescribed fixed image formation condition so that an attraction amount of toner attracting to the plural toner patches enter a prescribed range detectable for the optical detection device. The remaining toner patches are formed (based on an image formation condition determined) in accordance with the image formation condition previously adjusted. When the detection device detects the contribution factor, the entire toner patches are formed based on the prescribed fixed condition.

摘要： An image forming apparatus in which a predetermined image density can be obtained by correcting a toner density control target value without consuming toner. The output value Vt of the magnetic permeability sensor and the target output value Vtref are compared, and the toner density is controlled by controlling a powder pump on the basis of the comparative result thereof so that the output value Vt approximates the target output value Vtref. In addition, the target output value Vtref is corrected on the basis of the detected result of the image coverage ratio so as to maintain a predetermined development potential of the development apparatus. By virtue of this, even when image forming that involves a significant change in the toner replacement amount in the development apparatus is performed, for example, even when an image of high image coverage ratio is output, the toner density is adjusted to maintain the development capability at a constant, and a predetermined image density is ensured. Moreover, because the image coverage ratio can be detected without consuming toner, toner does not need to be consumed when the target output value Vtref is corrected.

摘要： An image forming apparatus in which a predetermined image density can be obtained by correcting a toner density control target value without consuming toner. The toner density of the developer is controlled so that an output value Vt of a magnetic permeability sensor approaches a target output value Vtref. In addition, the target output value Vtref is corrected in accordance with image coverage history information of output images transferred to a transfer paper and image coverage ratio history information of output images determined from the image coverage thereof and the size of the transfer paper. This history information comprises, for example, a cumulative average value of the image coverage or the image coverage ratio per transfer paper. It may also comprise a moving average value of the image coverage or the image coverage ratio per transfer material.
